3,5-Dimethylpiperidine → HCID 57263213, compound

Participants

Reaction Steps

62 G. of 3-(p-tert.-amyl-phenyl)-2,3-dimethyl-allyl bromide in 150 ml. of ether are added dropwise to a solution of 45.2 g. of 3,5-dimethylpiperidine in 200 ml. of absolute ether and the mixture is heated at reflux for 16 hours. The 3,5-dimethylpiperidine hydrobromide is removed by filtration and back-washed with ether. The ether solution is extracted with 2 N hydrochloric acid and made alkaline with 50% sodium hydroxide. The alkaline-aqueous solution is again extracted with ether, washed with water, dried over sodium sulfate and evaporated. By distillation, there is obtained pure 1-[3-(p-tert.-amylphenyl)-2,3-dimethyl-2-propenyl]-3,5-dimethylpiperidine having a boiling point of 155° C./0.04 Torr.
